Dwain Chambers’ High Court hearing has been postponed from Wednesday to Thursday this week.

The convicted drugs cheat is seeking to overturn his lifetime British Olympic Association ban which prevents him from competing in Beijing this summer.

Chambers, who had already beaten the qualification time, won the 100 metres in Saturday’s national trial.

Last week there was a preliminary hearing in the High Court when Lord Justice Mackay said he would hear an injunction from Chambers’ legal team challenging the BOA regulation preventing him competing in Beijing.

A full hearing and challenge against the bylaw is expected to be heard next March.

“These things happen and the date has been changed,” said Nick Collins, the athlete’s lawyer. “Although he doesn’t have to, it is planned for Dwain to attend court.”

Chambers will not be the only sprinter having to endure a further period of waiting for the decision.

Normally he and Simeon Williamson the runner-up would have gained automatic selection for the team.

Everything rests on the outcome of the hearing and if Chambers is successful the selectors have the right to name the third member.

Craig Pickering and Tyrone Edgar who finished third or fourth are the strongest contenders although grooming former world junior champion Harry Aikines-Aryeetey should not be ruled out. Their task if Judge Mackay decides against Chambers will be made easier if he loses as they will be able to name two additional team members.
